Title: Cermets and their production
IPC: H01B1/16
Filed: 1960-08-10
Abstract: A thin film of cermet material, e.g. at least 1000 <\>rA units thick, for protective coatings on heating elements, thermocouple protection tubes and resistors, includes a metallic component and an insulating component, such as a carbide, nitride, boride, silicide but preferably an oxide, intimately mixed and bonded together, and is made by simultaneously evaporating in an oxidizing atmosphere, preferably maintained at a partial vacuum inside a bell jar 10, e.g. at a pressure 2 x 10-5 to 2 x 10-4 mm. Hg., the two components, e.g. from crucibles 18 and 20, condensing the resulting evaporants on an independently heated substrate 11, e.g. heated at about 450 DEG  C. by means of an electric heater 9.  Heating of the substrate may continue after evaporation and the pressure may increase within the above limits for annealing the condensed evaporants.  As shown, the crucibles 18 and 20 are heated by coils 19 and 21, respectively to control the relative amounts of the components evaporated, and deposition on the substrate 11 is controlled by exposing selected areas of a mask 12 by operation of a shutter 15 controlled by knob 17.  An example is given of obtaining films by simultaneous evaporation of Cr and SiO2 in the proportions 80% and 20% by <PICT:0964263/C1/1> weight, respectively, wherein an oxide of Cr is formed which bonds together the other two components.  Other examples of cermet compositions are Al-AlO2, Ni-MgO, Ni/Fe alloy-Al2O3, and Al-MgO.  The substrate specified is a glass slide.ALSO:A thin film of cermet material, e.g. at least 1000 <\>rA units thick for protective coatings on heating elements, thermocouple protection tubes and resistors, includes a metallic component and an insulating component, such as a carbide, nitride, boride, silicide but preferably an oxide, intimately mixed and bonded together and is made by simultaneously evaporating in an oxidizing atmosphere, preferably maintained at a partial vacuum inside a bell jar 10, e.g. at a pressure of 2x10-5 to 2x10-4 <PICT:0964263/C6-C7/1> mm.

Title: Toxicants
Filed: 1947-10-20
Abstract: Salts are obtained by reacting, in the presence of an organic solvent for the end product, one or more straight-chain aliphatic primary amines with 8 to 18 carbon atoms with one or more of the following acids: benzoic, salicyclic, anthranilic and o-chlorbenzoic.  Simple or multiple water-soluble salts are thus obtained, and in addition one or more water-soluble organic acids may be present in the reaction mixture, e.g. acetic or lactic. The proportions of amine and acid are so chosen that the product is substantially a neutral salt. Preferred amines are n-dodecylamine, 9-octadecebylamine, and "coconut" amine (mixture derived from the fatty acids of coconut oil).  The organic solvent may be ethanol (95 per cent) or ethylene glycol monoethyl ether, and the solution of the salt obtained may be diluted to a 5 per cent solution in water.  Examples are given of the preparation of simple and multiple salts.ALSO:Fungicidal and bactericidal compositions are obtained by diluting with water an organic solution of a salt of a straightchain primary aliphatic amine of 8-18 carbon atoms with a water-insoluble organic acid (benzoic, salicylic, anthranilic, ochlorbenzoic).

Title: Derivatives of 7-aminocephalosporanic acid
Inventor: COWLEY BRIAN RICHARD
IPC: C07D501/38
Filed: 1963-07-15
Abstract: Derivatives of cephalosporin of general formula <FORM:1101424/C2/1> in which R1 is acyl and wherein the pyridine may be nuclear substituted, are obtained by reacting a sulphur compound of general formula <FORM:1101424/C2/2> in which R2 is acyl or hydrogen; -S-Y is the residue of a nucleophile and X is a cation; with pyridine or a nuclear substituted pyridine in a reaction medium containing dissolved therein a salt of mercury, silver or gold, said salt being able to complex with the pyridine reagent and to ionize in water, the resulting compound where R2 represents hydrogen thereafter being acylated.  The salt should preferably be an anion of a strong acid and should be non-oxidizing to compound V, e.g. the nitrate, perchlorate, trifluoroacetate and tetrafluoroborate. Instead of the metal salt and compound V, a salt of compound V with the metal or compound V with a complex of the metal salt with the pyridine reagent may be used. The reaction medium may be (a) aqueous or (b) non-aqueous.  For (a) water or a mixture of water and a water-miscible organic solvent is used at 20 DEG  to 100 DEG  C. Excess metal ions are removed by precipitation and purification is by percolation through an anion exchange resin. For (b) the reaction medium may be an alkanoic acid nitrile, a halogenated hydrocarbon, a nitroalkane, a nitro-aromatic compound, a cyclic ether, amides, e.g. formamide and N-methylformamide, N-methyl-pyrrolidone and a dialkylsulphoxide.  The reactants are heated at 50 DEG  C. and a solid, e.g. acetamide liquid at 50 DEG  C. may be used as reaction medium. Compounds of Formula V may be prepared by the methods of Specifications 1,012,943 and 1,059,562.  A wide range of acyl (R1) groups are mentioned including those of Specifications 1,054,806, 1,082,962 and in Specification 1,082,943.  Typical mercuric and silver salts include the perchlorate, nitrate, trifluoroacetate and tetrafluoroborate.  A complex of the pyridine reagent and the metal salt may also be used instead of the simple metal salts.
Patent GB-1551133-A (GB)
Title: Inverter stages in integrated injection logics
IPC: H01L27/07
Filed: 1976-07-06
Abstract: In an injection logic element, a lateral, bipolar pnp or npn transistor (1) is integrated with a vertical, bipolar npn or pnp transistor (2), respectively. In this arrangement, firstly, the collector (12) of the lateral transistor (1) is connected to the base (24) of the vertical transistor (2), and secondly, the base (13) of the lateral transistor (1) is connected to the emitter (22) of the vertical transistor (2). The object, in the case of a logic element of this type, is to increase the working speed. This is achieved by a diode (31) being connected in parallel to the base-collector junction of the vertical transistor (2) or, if a plurality of collectors (21, 23) of this transistor (2) are present, parallel to each of these junctions, which diode is poled in the same way as the base-collector junction in question. Strong saturation is thus avoided, and the storage time is reduced considerably as a result. Possible applications are found particularly in fast injection logic circuits.   <IMAGE>

Filed: 1937-10-15
Abstract: 485,532. Printing-machines. HADDAN, R. (Duplex Printing Press Co.) Oct. 15, 1937, No. 28147. [Class 100 (ii)] A rotary multi-unit printing press which comprises a number of interchangeable printing units and a folder unit or units is built up of a number of units capable of printing in multicolour, each unit being formed of a pair of impression cylinders 2, 2a mounted in fixed bearings, and printing-cylinders 1, 1a arranged below the cylinders and one or more colourprinting cylinders 1m arranged above the cylinders 2; 2a. The printing-plates are preferably of tubular form as described in Specification 19824/07, [Class 100], and are of two-page width. The printing-cylinders are mounted so as to be capable of being moved vertically by means of screws, and the cylinders 1m are mounted in pivoted hangers 5 carried by the screws 6b which effect the vertical adjustment. The cylinders 2, 2a are mounted in bearings formed in part in side frame members 3, and in part in blocks 3c secured to the members 3 by bolts 3d. The bearings 4a for the cylinders 1a are carried by hangers 4 adjustably secured to the blocks 3c by means of screws 4c which are tightened after the hangers 4 have been adjusted vertically relatively to the blocks 3c by means of screws 4d which are rotatably suspended in lugs 3e on the blocks 3c. When one of the printing-rollers 1m is to be put out of action, the screws 5c are moved outwards and the roller tends to move away from its impression cylinder under the action of gravity, and the cylinder may be held in non-operative position by a bolt 5e tapped in the side of the casting 5 which is caused to engage a groove 5f in the bolt 5c. When the bolt 5c is released from the locking bolt 5e, and the bolts 5c are tightened, the cylinder 1m returns to its original operative position and to the same degree of adjustment since this is controlled by the screws 6b. As shown in Fig. 2, a web is perfected in black and colour by being passed first around the roll 2 and then around the roll 2a, but the path of the web may be varied. Six units as shown arranged side-by-side in line will print a 24 page newspaper with impressions perfected in black and colour, and eight units will print a 32 page newspaper.
